A procedure based alternative to the injury severity score for major incident triage of children: results of a Delphi consensus process.

BACKGROUND: Triage at the site of a major incident is key to effective scene management. A number of triage algorithms have been suggested to assist the triage officer to determine triage priorities. However, many advocated scores were not specifically developed for use in major incidents, nor are they designed for multiple age groups. Many of these algorithms have not been validated: those that have were validated against the Injury Severity Score, which is of little relevance in a major incident--it is the urgency of medical intervention that is of importance in this setting. OBJECTIVES: To develop a set of criteria against which major incident triage algorithms can be tested. METHODS: Sixteen experts from the UK and South Africa took part in a three round Delphi consensus method in order to develop clinical criteria against which major incident triage algorithms may be tested. RESULTS: Thirty nine statements were initially identified as possible determinants of triage priority: 29 statements reached consensus. These associate specific clinical interventions with triage priority. CONCLUSION: Delphi may be used to identify which clinical criteria define triage priority in a major incident setting. These criteria and the associated triage categories may be used as for the validation of specific major incident triage algorithms. This method may be used to develop specific criteria for other triage algorithms.

Rabies: a review of UK management.

Rabies is endemic worldwide, and causes approximately 30 000 deaths per year. In the past 20 years, 12 deaths have occurred in the UK, although all but one case were contracted overseas. We have reviewed the current literature regarding the management of possible rabies exposure in the setting of a UK emergency department. The article offers an overview of rabies, including pathology, risk assessment, and current treatment, including both pre-exposure and post-exposure prophylaxis. We have also included a form online, which allows the correct information to be obtained and recorded prior to seeking advice from the local virology services.

Cerebellar abnormalities on proton MR spectroscopy in gluten ataxia.

Gluten sensitivity can manifest with ataxia. The metabolic status of the cerebellum was investigated in 15 patients with gluten ataxia and 10 controls using proton MR spectroscopy. Significant differences were present in mean N-acetyl aspartate levels at short echo time and N-acetyl aspartate/choline ratios at long echo time between the patient and control groups. These data support the hypothesis that cerebellar neuronal physiology differs between patients with gluten ataxia and healthy controls.

The South African experience with ingestion injury in children.

INTRODUCTION: The Red Cross Children's Hospital is the only children's hospital in South Africa. It has a dedicated trauma unit for all children under the age of 13 and serves a population of approximately 2 million inhabitants. As part of the Child Accident Prevention Foundation program we have kept a database of all children treated for trauma in our hospital since 1991. Presently, we have over 88,000 entries in our database. AIM: To study our experience with ingested foreign bodies in children. MATERIALS AND METHODS: A retrospective study was performed using the CAPFSA database of a total of 3677 patients presenting with foreign bodies. The hospital folders were searched using a standardised data extraction form. Only foreign bodies aspirated or ingested were included. RESULTS: To date, 241 folders have been analysed. DEMOGRAPHICS: Both sexes were equally affected (boys 49%). Age ranged between 0 and 12 years, although there was only one child under the age of 1. At the age of 3 years there was a peak in incidence (24% of all cases). Nature of ingested object: Although the objects were from a range of materials, most were metal (40%) or plastic (23%). The most commonly ingested object was a coin (28%), a ball (20%) or bone (8%). The size ranged from 0.1 to 3 cm (as measured by virtual ring), the most common size of an ingested foreign body was 0.5 cm. Anatomical site: The most common anatomical site of impaction was the nose (41%), followed by the oesophagus (20%), the stomach (14%) and bowel (11%). Other anatomical sites included hypopharynx, nasopharynx, bronchus, larynx and oral cavity. Severity of symptoms: Only 0.4% of our cases were assessed as being severe, 14% as moderate, and 44% as mild. Forty-two percent (42%) had no symptoms. Removal: Fifty-seven percent (57%) of ingested foreign bodies were removed surgically, 19% were left in situ, 14% spontaneously dislodged and only 1% was removed by Foley catheter manipulation. CONCLUSION: A presentation with a foreign body is quite common in our patient population, representing approximately 4.2% of all our cases. The majority of ingested foreign bodies produced mild or no symptoms, needed surgical removal and had no complications.

Diagnostic angiography performed by nurses.

The aim of this study was to assess the feasibility of a nurse performing diagnostic angiography. After a theoretical and practical training course on the techniques of arterial catheterization, the nurse performed diagnostic angiography under supervision on 68 patients. Patients with impalpable femoral pulses or scarred groins as well as obese patients were excluded. Successful arterial catheterization was achieved in 58 (85%) patients. Complications were limited to a severe haematoma requiring surgery in one patient and seven minor self-limiting haematomas. On this evidence, it is feasible and safe for appropriately trained nurses to perform angiography in radiology departments that have limited radiology staffing levels and no non-invasive alternations to catheter-based angiography.
